6240B DC Voltage Current Source/Monitor Operation Manual
5.2.5 Source Function

2. Restrictions on the load current pulse in voltage source
When the load current exceeds
1 A, the hardware is restricted as follows:
1. Restriction on the load current pulse width
Tw: Load current pulse width
Ip: Load current
Vo: Output voltage
2. Restriction on the duty ratio of load current pulse
Range is the same as the pulse duty ratio restriction described in *1, Step 2.
NOTE:
If the load current beyond the restrictions is applied, the unit will detect overload and set
Standby status. To prevent damage to the 6240B, do not apply a load current that exceeds the
above restrictions.
